In this now-viral video, Wyatt and his trainer, Nate, jump on the trampoline together. Wyatt lets the experience settle, then flings his arms in the air with joy. And once he really gets the hang of things, he belts out a loud "Faster!" and everyone in the video starts laughing.

In addition to jumping on the trampoline for the first time, Wyatt's mother, Allison Burggraff, loves what the gym has been able to offer her son. "They empower him with affirming words; they tell him he is strong, brave, and courageous," Allison told Good Morning America. "When Wyatt has gone through medical issues — getting an IV or MRI — we can say to draw on that experience and say, 'You can do hard things.'"
